For all of U who goes for trophies.
It's an really easy way for boost all online trophies alone(except for arena master and slayer).
You need to setup an online private match.Mode ctf,training level,1 hour and unlimited score(0 points).Its just few hours grind now,because one capture=200points).And most of all,you can do it ALONE.
